Sudo broken, sudo fixed

Linux and Mac OS X users and system administrators, and long before them, Unix users and sysadmins, have used sudo as an essential computer management tool. With it, users are given the power to make essential, but sometimes dangerous, changes to their systems. Recently a fundamental security bug in sudo was discovered, In some network this security hole could allow a cracker unlimited control of Linux, Mac OS X, and Unix systems. Fortunately, the bug has now been fixed.

Sudo, which system operators (sysops) use all the time, has been around for almost as long as Unix has been. People often think sudo stands for “do as superuser.”
